Sawyer Sweeney is a rebellious southern belle whose latest scandal has her back in her overbearing mama's house. She's fresh off a broken engagement and decides to swear off all the men in Hollis, her small Mississippi town.

Austin Sweeney is Sawyer's gorgeous older brother who left a trail of broken-hearted belles behind when he took a job in South Carolina after college. Austin decides to come back to Hollis for two weeks to check in on his broken-hearted sister and brings his work colleague Ryan, along with him. Austin warns Ryan to stay away from his vulnerable sister, which Ryan easily agrees to since their job doesn't allow for relationships.

When Ryan accidentally reveals the real reason Austin is in town, Sawyer struggles to keep it a secret. She learns Austin and Ryan are agents in the F.B.I and their latest target is Sawyer's ex-best friend, Whitney Carmichael's uncle. Sawyer sees it as an opportunity to get revenge on her old pal, but big brother Austin refuses to let her get involved with their undercover work. Ryan sees Sawyer as a valuable resource so he agrees to let her help, all while keeping her involvement a secret from Austin.

Can Sawyer keep her secrets straight and stay focused on the task at hand? Or can Ryan keep his promise to Austin and stay far away from his reckless sister? If not, Sawyer might end up in another scandal and left behind with only her broken heart.
